Outline is a note-taking application that features a unique design, intuitive hierarchy, and free placement of notes like a paper notebook, support for various types of content (text, images, inks, tags, Web content, etc.), synchronization options, and Microsoft OneNote compatibility. Outline's hierarchy resembles that of a real notebook: there are notebooks for general subjects, section tabs for specific topics, and pages for actual notes. For more complex notebook structures, additional section groups can be created within a notebook. There are no limitations on the number of notebooks, section groups, section tabs and pages.

The Go Programming Language (Go) is an expressive, concise, clean, and efficient language with concurrency mechanisms that make it easy to write programs that get the most out of multicore and networked machines. Its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It's a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language.

twyg lets you visualise arbitrary tree structures in a pretty way. The appearance of the tree (layout, color, node, connection shapes, etc.) is fully controlled via configuration files in a generative way. This means that almost all visual properties of the output can be controlled by expressions that depend on the characteristics of the tree (e.g. the color or shape of a node can be a function of its hierarchical position in the tree). This allows for crafting very flexible configurations that can be applied to trees of arbitrary size and complexity. It supports the Cairo and NodeBox1 rendering backends.

etmTk is an event and task manager. In contrast to most calendar/todo applications, creating items (events, tasks, and so forth) in etm does not require filling out fields in a form. Instead, items are created as free-form text entries using a simple, intuitive format and stored in plain text files. Both a graphical user interface based on Tkinter and a command line interface are provided.

JSON-delta is a multi-language software suite for computing deltas between JSON-serialized data structures and applying those deltas as patches. It enables separate programs at either end of a
communications channel (e.g. client and server over HTTP, or two processes talking to one another using bidirectional IPC) to manipulate a data structure while minimizing communications overhead. Robust reference implementations are available in Python and Javascript. Work is ongoing on other implementations, including Racket and Perl.

Skylable SX is a reliable, powerful, fully distributed cluster solution for your data storage needs. It can aggregate the disk space available on multiple servers and merge it into a single storage system. The cluster makes sure that your data is always replicated over multiple nodes (the exact number of copies is defined by the sysadmin) and synchronized. It has built-in support for deduplication, client-side encryption, on-the-fly compression, and much more.

Ada EL is a library which implements an expression language similar to the JSP and JSF Unified Expression Languages (EL). The expression language is the foundation used by Java Server Faces and Ada Server Faces to make the necessary binding between presentation pages in XML/HTML and the application code written in Java or Ada.
